.hndiusd on filed November 30, 1885. Serial No.194fl38. (No moth-Li To all whom it 11mg concern.-

Be it known that we, JOHN T. UN'UERWOOD, a citizen of the United Brooklyn, in the county of Kings and State n 5 New York, and CoLBoRNn BROOKES, 1.

subject of the Queen of GrcatBritain, residing at Jersey Zity, in thc county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Inki'ng-Riblions or ltlarking-Bands to be Employed in \Vriting-Maehines, Type WVriters, &c., of which the following is a Specification.

Our invention relates to improvements in ribbons or marking-bands adapted to be our ploycd in writing-machines, type-writers, and other analogous machines for the production of letters, figures, or designs by the interposition between the type or marking device and the surface to be marked upon of an inked, saturated, or coated ribbon or marking-band.

The object of our invention is, first, to enablcan operator on a writing-machine, typewriter, or analogous machine to produce letters, figures, designs, or marks of different 1 colors on the same line oron -differentlines or portions ofthe same page, sheet, or portion of material without necessitating thercmoval of the ribbon or band used to produce one color and the substitution ofanothcr ribbon or tra'versing surface to produce another color.

The object of. our invention is also to enable operators on writing-machines, type-Writers, or other analogous iifra'cliines to produce documents, writings, figuieinor designs consecutively, alternately, or othdrwise on differentshcets of material in the saline color, but of different (,hZ-IIZIGtCIS and for d-iilhrent purposes. Forinstance, by the use of this invention an operator with the same machine andwithoutremoving tbcmarking meant can produceflirst, a letter, document, design,&c., in permanent or record ink 3 second, a letter, document, design, 830.,

in copying-ink; and, third, a letter, document,

or, design in lithographic-ink upon prepared paper ready to be. transferred to a stone for the purpose of reproduction in large numbers.

In carrying out our invention We employ a .ribbon or band having two, three, or other States, residing at,

the fabric.

'of Figs. 3 and number of parallel sections arrangcd'sidc by" side, such sections being by preference each of a different color or character from the rest. We can, however, in. some cases employ two sections of the same color or character and one or more sections of a diiferent color or character. This will be particularly the case where one color or character of marking-surface predominates in use over another color or character of markingsurface. 1

In some cases we employ a ribbon or band composed of two or more separate sections adapted to be employed in place. oftwo or other number of conjoined sections.

The accompanying drawingsformpart of" thisspccification and indicate some of the best means of carrying out our invention. Figure 1 represents a perspeetiveview of part of a type-writer with one ofourimproved ribbons applied thereto. Fig-2 is a plan View: of a pair one of our improved ribbons adapted to print in three colors or descriptions of marking matter. Fig. 3 is a plan View of a portion-of ribbon, illustrating one mode of manufacturing Fig. 4 is an enlarged crosssection of Fig. 3. Fig. 5 shows a slight modification 4. Fig. 6 shows another slight modification. a

In each of the views similar letters of refercnce are employed to indicate corresponding parts in all the figures wherever they occur.

, A. represents part of the main framing of a type-writer of the style commonly known as the Remington TypeNriter, and B one of the type-levers, which is provided with type b, of the ordinary or suitable character.

0 represents a ribbon,which in the arrangement shown is supported on bobbins D D, and has its printing or marking surface arranged in three parallel sections, 0 c'c, each of which is ofa different color or character. ,For instance, the ccnter section, a, maybe black, the section 0 may be red, and the section 0 blue; or, the section a? may betcoated, saturated, or prepared withv pcrmaifent or rec- 0rd ink, the section b with lithographic ink adapted to produce impressions on a surof bobbins and guides supplied with face ready to be transferred to a stone, and the third, 0, may be prepared with copyingink. l

' In Fig.2 we have shown a continuous web of fabric, thethree sections of which are coated or saturated with three different colors or descriptions of marking material, which are allowed in the course of manufacture to come directly in contact one with the other. The material is supplied to the ribbon bybrushes, rollers, or other suitable devices.

Figs. 3 and 4 represent a slight modification, in which the fabric is woven, with soft thick warps c c interposed at the point of junction of the sections, the object of which thick warps a? is to prevent the ink or other material when in a liquid state from mixing with or flowing from one section onto the other.

These warps c are subsequent] y pressed down flat by rollers or other suitable means.

Fig. 5 is another modification, in which the ink or other material witlrwhioh the sections of the ribbon .are coated or saturated inthe course of manufacture is prevented from spreading from one section to the other by the surface of woven fabricin some cases we form the same of paper, leather, or other suitable material adapted to receive and retransmit a marking material applied to its surface.

In use our improved ribbons or markingbands may be controlled in position by any suitable means, so as to bring the desired sec tion in place tr. be interposed between the type or marking device and the surface to be printed or marked upon; but we prefer to usea device of a character such as described and shown in"v an application for Letters Patentv filed by us simultaneously with this application 'for improvements in type-writers, &c.

Our improved ribbons or marking-bands may be used with writers employed for telegraphic purposes,and also with stamping and other analogousdevices for effecting impressions by the interposition of a marking-band of ribbon between the marking device and the surface to be marked upon.

Although we have shown our ribbon or band of 'ribbonapplied to a Remington type-writer, itis equally applicable to all other type-writers by a slight modification of or addition to their existing parts. I

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

. 1. Aprinting or marking ribbonor band composed of a plurality of connected parallel sections, each section being coated or saturated with printing or marking material of different color or eharacter,and adapted to be employed intermittently at will or continuously .in posi-,

tion in a type-writing or marking machine to produce the desired coloror description of impression, substantially as andl'or the purpose stated. I

2. Aprinting or marking ribbon or band having a plurality of parallel sections provided with printing or marking material of different colors or character, each adapted to be employed intermittently at will or continuously in position in a writing or marking umchine, the coated orsaturated surfaces oftheseetions of the said ribbon or band being separated one from the other by a dividing means, c, substantially'as shown and described.

In witness whereof we have hereunto set our hands this 28th day of November, 1885.
